Engineering in most industries, still tends to be primarily dominated by males. When I first entered the field of Printed Circuit Board (PCB) engineering, it was a bit intimidating. This was because the men always outnumbered the women. I felt we were graded on separate standards "Men vs Women".

When creating your optimal circuit board design, one factor that must be considered is the solder mask and whether to go with matte finish solder mask or gloss finish mask for your final product. Usually, most designers don't specify their preference and end up leaving the decision to the PCB fabricator. Most fabricators will likely default to a gloss surface finish, the more popular choice of the two.

One point that anyone involved with cable assemblies understands is that "every electronic or mechanical component will eventually reach the end of its life cycle". This blog post will define cable assembly obsolescence as the point in an assembly’s life cycle when it is either no longer in a usable state, meaning it is not functioning as it was designed, or there is no longer a use for the cable assembly due to technology changes.

When we sat down in 2005 to develop our IT infrastructure plan for the company, I was unsure of why we spent so much time evaluating every investment in terms of what we would do in case of a disaster. Well, this winter, I found out why that was so important.

Two distinct types of polyimide flex core material constructions are utilized in today’s flex circuit manufacturing: adhesive based and adhesiveless. The difference, as you can probably tell from the name, is the method used to attach the copper layers to the polyimide core. This creates a unique set of material properties for each of the material types which must be factored into designs to meets all requirements and remain cost effective.

This blog post addresses custom user interface testing in terms of functional test schemes that are completed prior to shipment. Generally, the first user interface assemblies shipment are for First Article acceptance testing where customers fully examine the first units for mechanical and electrical compliance to all engineering drawing and specifications.

When you consider and evaluate the true stresses that lithium batteries encounter, most battery packs are designed to last three to five years if used and stored properly. Environmental conditions, not just charge cycling, are the key factors for longevity. The worst situation is keeping a fully charged battery at elevated temperatures. When not in use, batteries must be stored in a cool place.

When we think of manufacturing in the 21st Century, we picture automated machines rapidly pumping out new products with ease. So why can't the process of complex wire harness manufacturing become fully automated as well? To answer this question, we need a deeper understanding of cable harnesses and how they are prepared.

A cable harness, also referred to as a wire harness, cable assembly, wiring assembly, or wire loom, is a grouping of wires and/or cables that are used to transmit signals as well as provide electrical power if needed. The wires and cables are joined together using a combination of straps, cable ties, cable lacing, tubing (either shrink tubing or non-shrink tubing), sleeving, electrical tape, conduit, and braided extruded string.

When designing PCBs in a multi-up array, most designers choose v-score (also referred to as v score, v cut, or v groove) as the singulation method over traditional rout and breakaway tabs. The benefits of v-scoring pcb range from effortless removal of parts from panel form to realized cost savings with better utilization of panel area. When designing circuit boards in array with v-scoring, there are two areas of concern - the angle of the cut, and the depth of the cut.
